2. INDUSTRIAL HYGIENE
Industrial hygiene is the science of
anticipating, recognizing, evaluating, and
controlling workplace conditions that may
cause workers' injury or illness. Industrial
hygienists use environmental monitoring and
analytical methods to detect the extent of
worker exposure and employ engineering,
work practice controls, and other methods to
control potential health hazards.

4. Cause of INDUSTRIAL HYGIENE
 Sickness
 Impaired Health andWellbeing
 Significant Discomfort
 In-efficiency among workers or
among citizens of community

5. Relation Between OSHA and
Industrial Hygiene
 Under the Act, OSHA develops and sets
mandatory occupational safety and health
requirements applicable to the more than 6
million workplaces in the U.S. OSHA relies on,
among many others, industrial hygienists to
evaluate jobs for potential health hazards.

6. Some Examples of Job Hazards
To be effective in recognizing and evaluating
on-the-job hazards and recommending
controls, industrial hygienists must be familiar
with the hazards' characteristics. Major job
risks can include air contaminants, and
chemical, biological, physical, and ergonomic
hazards.

8. Chemical Hazards
 Harmful chemical compounds in the form of
solids, liquids, gases, mists, dusts, fumes, and
vapors .Some are toxic through inhalation and
some of them irritate the skin on contact; some
can be toxic by absorption through the skin or
through ingestion, and some are corrosive to
living tissue.

9. Physical Hazards
 These include excessive levels of noise, vibration,
temperature etc.
In occupations where there is exposure to
ionizing radiation, time, distance, and shielding
are important tools in ensuring worker safety.
Danger from radiation increases with the
amount of time one is exposed to it; hence, the
shorter the time of exposure the smaller the
radiation danger.

10. Biological Hazards
 These include bacteria, viruses, fungi, and
other living organisms that can cause acute
and chronic infections by entering the body
either directly or through breaks in the skin.
Occupations that deal with plants or animals
or their products or with food and food
processing may expose workers to biological
hazards. Laboratory and medical personnel
also can be exposed to biological hazards.

12. TOXICITY HAZARD
 Inhalation -Vapor ,mist or dust
 Absorption - Skin or eyes
 Oral - Ingestion
 Carcinogenic

14. MECHANICAL HAZARDS
 Over pressurization
 System leak
 Rotating/moving equipment's
 Thermal burns
 Noise generation
 Equipment/utility failure

16. How do IH's Recognize and Control
Hazards?
 Industrial hygienists recognize that
engineering, work practice, and
administrative controls are the primary
means of reducing employee exposure to
occupational hazards. Engineering controls
minimize employee exposure by either
reducing or removing the hazard at the
source or isolating the worker from the
hazards.

17. Steps to Protect Employees
 Anticipate potential hazards
 Recognize potential hazards
 Evaluate exposure and risk
 Control exposure and risk
